Experimental Research on Mineral Processing of an Argillaceous Porphyry Copper-Molybdenum Ore in Yunnan
摘要
Abstract
A porphyry copper-molybdenum ore mine in Yunnan processes 38 000 t of raw ore per day.Affected by surface subsidence,the intrusion of glacial till has increased the mud content of ore,which seriously restricts mineral processing indexes.Without revamping the existing process,orthogonal tests were carried out to determine the reagent regime suitable for argillaceous ore:lime dosage of 300 g/t,collector MCO of 94 g/t and foaming agent HCCL of 30 g/t.Closed-circuit tests were conducted under the optimized reagent regime,achieving favorable indicators with copper grade of 24.35％and copper recovery of 92.76％in copper concentrate.Compared with the results before optimization,the copper grade of concentrate increased 1.0 percentage point,0.71 percentage point.This study provides an experimental basis for reagent adjustment in the on-site production of argillaceous copper-molybdenum ore.关键词
